A student was given a sample to observe under the microscope. He observed and found that the sample is the most common type of spore involved in asexual reproduction in algae. Identify the spore.

Asexual reproduction (in algae) is by the production of different types of spores, and the most common type is zoospore. Zoospores are flagellated (motile) and on germination give rise to new plants.
